For most of the twentieth century, people communicated by telephone or by letter. This is now changing, and e-mail is becoming the preferred way of communication. It’s faster than traditional one. 【小题1】 As e-mail is becoming popular, here are some rules we need to know.

Be polite and friendly.

Start your message with a greeting (问候). If you are writing to a friend, you can begin with “Hi Sandra.” If you are writing to your teacher, begin your message with “Dear Mr. Atonso.” 【小题2】 Many people just type their names. Others say Bye, Cheers, or use abbreviations (省略语) like BFN (bye for now).

Look good

When someone receives an e-mail message from you, they might not know anything about you. 【小题3】 So make yourself look good. Type your message, and then read it again. Sometimes sentences seem clear when you write them, but they don’t make sense when you read them back.

【小题4】

If you start to use your e-mail several times a week, your message box will soon be filled with e-mails. After a few weeks, you can have a list of 60 or 70 messages. It is easy to delete the message you don’t want any more. 【小题5】 If you don’t know how to do that, just ask your friends for help. It only takes a few minutes to learn.

Many of us don’t pay much attention to the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why our eyes should be given a lot of care. Natural eye care should be put in the first place.

There are several causes leading to poor eyesight like not eating enough food, genes and aging (老化).

Televisions, computers and reading are also the causes of having poor eyesight. If you happen to work in front of a computer, you’d better take a break every once in a while.

Something dirty can cause redness and it will make you feel uncomfortable. It is bad for your eyes, too. If this happens, the best way is to clean your eyes by using cold water. You must also try your best to protect your eyes from harmful things. For example, sunglasses are not just for fashion but they can also serve as a great way to protect your eyesight from UV rays.

Eating healthy food will do good to your eyesight. Remember that vitamins A, C and E are good for the eyes. Try to eat food groups that have these vitamins. And you should do eye exercises because they protect your eyesight, too. If a person exercises regularly and eats the right kind of food, his eyes will stay in good condition for a long time.

All above are natural ways of eye care that help us keep healthy eyes. Being happy all the time can be helpful to a person’s eyesight, too. In a word, eye care is very important, no matter how old a person is.
